Magnesium

The Territory has significant development opportunities close to Darwin with potential to supply magnesia markets at scale.

Prospectivity

The Territory has significant magnesite deposits located near Batchelor in the Pine Creek Orogen, 75 km south of Darwin. Thessally Resources Pty Ltd’s Huandot and Korab Resources Ltd’s Winchester deposits occur as stratabound bodies within the Celia and Coomalie Dolostones, and are located close to infrastructure and the Darwin Port. Both projects are undergoing scoping or feasibility studies including investigation of downstream processing options to produce caustic calcined magnesia and/or magnesium metal.

Thessally Resources’ high-grade Huandot magnesite deposit is just 80 km south of Darwin Port, proximal to road, rail, solar power and gas infrastructure. Huandot’s magnesite resources are amenable to low-cost mining and simple processing. Recent drilling has demonstrated mineralisation is open along strike and to depths of more than four times the limits of the existing resource model, providing confidence for the potential for significant expansion of the current Mineral Resource estimate. The project is permitted for bulk sampling, with baseline studies underway for mine permitting. Thessally Resources is progressing studies for a low-impact, staged development path (direct shipping magnesite ore, calcined magnesia and ultimately magnesium metal).
